StylePrefix property not overiding the gjs in most elements with the gjs-class

Thanks for reporting this, @JonathanRiche. Great question about stylePrefix property not overiding the gjs in most elements with the gjs-class.

Describe the bug

How to reproduce the bug?

Modify the stylePrefix property on any of the options in the config option when running the grapesjs.init() function ie

layerManager:{
  	stylePrefix:'customStylePrefix'
  },
  blockManager: {
  stylePrefix:'customStylePrefix'        
 }

What is the expected behavior? Expected behaviour is for the .gjs-classes are replaced with the stylePrefix like previous versions of grapesJs

What is the current behavior? Current behaviour is the stylePrefix property is not being applied even when setting in the config

If is necessary to execute some code in order to reproduce the bug, paste it here below:

const editor = grapesjs.init({
	//stylePrefix:'customStylePrefix',  
	container: '#gjs',
  fromElement: 1,
  height: '100%',
  storageManager: { type: 0 },
  plugins: ['gjs-blocks-basic'],
  layerManager:{
  	stylePrefix:'customStylePrefix'
  },
  blockManager: {
  stylePrefix:'customStylePrefix'        
 }
});

Thanks for reporting this, @JonathanRiche.

Great question about stylePrefix property not overiding the gjs in most elements with the gjs-class. The recommended approach with StyleManager is to use the event-driven API.

Start here:

Check the GrapesJS documentation for your specific module
Look for the on() event listener method
Most operations can be achieved by listening to editor and component events

Common patterns:

// Listen for changes
editor.on('change', () => console.log('something changed'));

// Component lifecycle
editor.on('component:mount', (c) => console.log('component ready', c));
editor.on('component:update', (c) => console.log('component updated', c));
